General Description
The EL2009 is a patented high speed bipolar monolithic buffer
amplifier designed to provide currents over 1 amp at high fre-
quencies while drawing 40 mA of quiescent supply current The
EL2009’s 3000 V
ms slew rate and 90 MHz bandwidth driving a
10
X load insures stability in fast op amp feedback loops Elan-
tec has applied for patents on unique circuitry within the
EL2009
Used as an open loop buffer the EL2009’s low output imped-
ance (1
X) gives a gain of 099 when driving a 100X load and 09
driving a 10
X load
The EL2009 has an output short circuit current limit which will
protect the device under both a DC fault condition and AC op-
eration with reactive loads
The EL2009 is constructed using Elantec’s proprietary Comple-
mentary Bipolar process that produces PNP and NPN transis-
tors with essentially identical AC and DC characteristics In the
EL2009 the Complementary Bipolar process also insulates the
package’s metal heat sink tab from all supply voltages There-
fore the tab may be mounted to an external heat sink or the
chassis without an insulator
The EL2009CT is specified for operation over the 0 Cto a75 C
temperature range and is provided in a 5-lead TO-220 plastic
power package
